1 This invention relates to certain new and useful improvements innursing bottles.

The invention contemplates the employment of a valve controlled stemarranged in a nursing bottle to facilitate the explusion of the contentsfrom the bottle with less effort when the bottle is held upright ortilted, with the result that substantially all of the contents of thebottle may be expelled during the nursing operation.

The invention also contemplates a nursing bottle of the descriptionherein more fully set forth, which comprises relatively few parts,resulting in economical manufacture and assembly.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings showing the preferred form of construction, and in which:

Fig. 1 is a vertical sectional detail View of the invention;

Fig. 2 is a vertical sectional detail view of the invention similar tothat shown in Fig. 1 but showing the nursing bottle in a reversed tiltedposition; and

Fig. 3 is a fragmentary sectional detail view of the nursing bottleembodying my invention, illustrating a modified form of construction.

The several objects of my invention are best accomplished by thepreferred form of construction now to be described.

Referring more particularly to Figs. 1 and 2, a bottle is indicated atID. This bottle may be formed of any approved material and is preferablyprovided with a bowl shaped interior bottom H and a neck l2. Threadedinto this neck I2 (or frictionally mounted therein, as may be desired)is a plug l3 having a reduced portion Hi to provide a flange I5, whichbears against the adjacent portion of the neck l2. Threaded into thisplug I3 is a stem l6 providing a reduced portion H on which is slidablymounted a valve sleeve I8, limited in its movement to a position toclose an opening l9 by a collar formed on the stem 16. The stem I6 ishollow in construction and may be formed of any suitable mate- In thepresent instance, the stem, as shown in Fig. 1, extends well into thebowl-shaped bottom ll so that when the bottle I5 is used in the positionshown in Fig. 1, substantially all the contents of the bottle will bedrawn therefrom.

The neck l2 provides a bead 2| and over this bead 2| is adapted to beyieldably positioned a nipple 22 of any approved construction.

When the bottle is used in a substantially upright position, as shown inFig. 1, or inclined from such position, the sleeve l8 will rest upon thecollar 20 closing the opening 19 so that the contents of the bottle mustbe drawn through the stem l6.

However, when the bottle is in the position shown in Fig. 2, the sleevel8 will move in a position against the plug I3 from closing positionwith respect to the opening l9, thereby allowing the contents of thebottle ill to flow through the opening I!) into the nipple 22.

A nursing bottle constructed with a feeding stem similar to thatindicated at It aifords removal of substantially all the contents of thebottle regardless of which of the two positions the bottle is held inand greatly facilitates the extraction of the contents from the bottleduring the nursing operation.

The parts are easily removable so that they may be cleaned andsterilized.

In Fig. 3, I have illustrated a slightly modified form of construction.In the illustration in Fig. 3, parts therein shown which are similar tothose illustrated in Figs. 1 and 2, are indicated by similar referencenumerals. The construction in Fig. 3 differs from that shown in Figs. 1and 2 in that the plug l3 provides above the flange IS a curvedextension 23 which disposes the nipple 22 at an inclination with respectto the longitudinal axis of the bottle In. The advantages and theresults of the construction shown in Fig. 3 are otherwise the same asthose resulting from the construction shown in Figs. 1 and 2.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modifications without departing from the spiritof theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having thus described my invention, what I claim as new and desire toprotect by Letters Patent is:

1. A nursing bottle providing a neck, a plug mounted in the neck, ahollow stem carried by the plug and extending into the bottle and havingan opening formed therein adjacent to and below said plug, and a valvesleeve slidably mounted upon said stem for controlling passage throughsaid opening.

2. A nursing bottle including a neck, a plug in said neck, a hollow stemextending from said plu into said bottle and terminating at a pointadjacent to the bottom of said bottle and having a reduced portion withan opening formed therein adjacent to and below said plug, and a collarslidably mounted on said reduced portion for controlling pasage throughsaid opening.

3. A nursing bottle providing a neck, a plug mounted.- in the neck, ahollow stem carried by the plug and extending into the bottle and havingan opening formed therein adjacent to and below said plug, and a valvesleeve slidably mounted upon said stem for controlling passage throughsaid opening, said stem providing a collar for limiting movement of saidsleeve to closing position with respect to said opening.

4. A nursing bottle including a neck, a plug in said neck, a hollow stemextending from said plug into the bottle and. terminating at a pointadjacent to and in spaced relation with respect to.

the bottom of said bottle and having a reduced portion with an openingformed therein, and a collar slidably mounted on said reduced portionfor controlling passage through said opening, said stem providing acollar for limiting movement of through said. opening.
